A commercial refinance is a purchase: you pay closing costs plus whatever prepayment penalty the old loan charges, and in exchange you get a lower payment. It pays only if you hold the property long enough for the monthly savings to repay that purchase price — and on commercial loans the penalty is often large enough to decide the question by itself. This page owns the decision: the triggers worth acting on, the break-even formula every lender guide uses, and two worked examples on the same loan — one where refinancing pays comfortably, one where the penalty makes it pointless.
General information, not financial advice.
Refinance conversations should start from a reason, not a rate advertisement. The triggers lender guides converge on (Axiant; passycapital): market rates roughly 75–100 basis points below your current coupon; a balloon falling due inside 6–12 months; property performance improved enough to push DSCR past ~1.20–1.30×; an exit from bridge or hard-money debt onto permanent terms; or cash-out for a defined, return-bearing use. Rate-and-term and cash-out refinances run on different logic — for cash-out, the test is not payment savings but whether what the capital earns beats what the new debt costs — but both start here.
$$ \text{Break-even (months)} = \frac{\text{closing costs} + \text{prepayment penalty}}{\text{monthly payment savings}} $$
Refinance only if your remaining hold comfortably exceeds the result. Closing costs run roughly 2–5% of the loan amount (itemised line by line in commercial real estate closing costs). Two things to hold before you compute anything: the exact payoff statement from your current lender — balance, accrued interest and the penalty as actually calculated, not as you remember the clause (Axiant’s step guide puts this first) — and the penalty’s definition, which lives in commercial mortgage terms and balloons. This page prices penalties; that page defines them — step-down, yield maintenance and defeasance are very different numbers on the same balance. On CMBS loans, yield maintenance alone is reported in the $50,000–$200,000+ range on mid-size balances (commercialloansoftexas, market colour).
A $1,500,000 loan at 8.25%, 25-year amortization, 10-year term — payment $11,826.75/month. After 48 payments the balance is $1,414,233.13. The loan’s 5-4-3-2-1 step-down is in year 5, so the prepayment penalty is 1% = $14,142.33. A new loan at 6.90% on a fresh 25-year amortization pays $9,905.47/month.
| Item | Amount |
|---|---|
| Monthly payment savings | $1,921.28 |
| Prepayment penalty (1% step-down) | $14,142.33 |
| Closing costs (2.5% of the new loan) | $35,355.83 |
| Total cost of refinancing | $49,498.16 |
| Break-even | 25.8 months |
Check it on interest, not just payments: over the next 72 months the old loan would charge $656,369.40 of interest against $555,552.31 on the new loan — $100,817.08 saved — and the refinance also removes the old balloon of $1,219,076.39 that would have fallen due at month 120. Verdict: pays, comfortably, for any hold beyond about 2.2 years.
The same loan, refinanced early at month 18. The balance is higher — $1,471,090.72 — but the real damage is the calendar: the step-down is in year 2, so the penalty is 4% = $58,843.63. Closing costs at 2.5% are $36,777.27, for a total of $95,620.90. And the rate only improves to 7.75%: new payment $11,111.57, savings of just $715.18/month. Break-even: 133.7 months — longer than the 102 months left to the old balloon, and longer than most holds. The refinance never pays back before the debt it replaced would have matured anyway.
The lesson is not “don’t refinance early”; it is that the penalty, not the rate, decides. Timing a refinance to the open window — typically the last 3–6 months before a balloon, or just after a step-down rung expires — is often worth more than the rate move itself. In Case A, waiting for the 1% rung turned a six-figure obstacle into a minor line item.
Sequence matters because the penalty clock is running. Get the payoff statement first — it fixes the penalty to a number rather than a clause. Then take quotes on the same structure (same balance, same amortization) so the payment comparison is honest, and run the break-even on each. Finally, check the calendar before the rate sheet: if a step-down rung expires or an open window opens inside the next few months, model the deal at that date as well. In Case B’s position, waiting for the calendar was worth more than the entire rate improvement on offer. One more practical point: a refinance is a new underwriting, not a formality — the lender re-tests coverage on current financials, which is why the DSCR trigger above matters. A property whose coverage has slipped may not qualify for the loan its owner is trying to leave for, even at a rate the market advertises.
Payment savings are not interest savings. A refinance restarts the amortization clock, so part of any payment drop is just the same debt stretched over a fresh 25 years — the payment falls even in deals where lifetime interest rises. That is why both cases above are cross-checked on interest over a fixed window, and why you should run the same check on any quote you are shown. The DSCR side of the decision — whether your property’s improved coverage is what unlocks the better terms — is covered in how commercial lenders evaluate your loan. This page deliberately does not re-price today’s rates; the dated snapshot is on the commercial real estate loan rates page.
When should you refinance a commercial property? When a real trigger is present: rates roughly 75–100 basis points below your coupon, a balloon due inside 6–12 months, coverage improved past about 1.20–1.30×, an exit from bridge or hard-money debt, or a defined use for cash-out proceeds — and when the break-even lands well inside how long you will actually hold the property.
How do you calculate the break-even point on a commercial refinance? Add the closing costs and the prepayment penalty on the old loan, then divide by the monthly payment savings. The result is the number of months the savings need to repay the cost of switching. If your remaining hold is not comfortably longer than that figure, the refinance does not pay.
Can a prepayment penalty make refinancing pointless? Yes — it is the most common deal-killer. In Case B above, a 4% step-down penalty of $58,843.63 pushed the break-even to 133.7 months, beyond the old loan’s own remaining life. The same loan refinanced after the penalty stepped down to 1% broke even in 25.8 months. The penalty schedule, not the rate quote, is the first document to read.
